A metal fish decal that parodies the christian jesus fish that lots of people put on the back of their cars. It says 'DARWIN' inside the body of the fish and has feet, symbolizing the evolution of the species. Sometimes these fish have other things inside them, like the word 'Evolve'.

Because I believe in evolution and not creationism, I display a darwin fish on the back of my car.

Stupid bullshit badge that stupid, petty atheists put on their car to one-up stupid, petty Christians and their Jesus fish, itself being one-upped by the stupid, petty Christians adorning their vehicle with a plastic badge of the stupid, petty Jesus fish eating the stupid, petty Darwin fish. The only worthwhile fish-badge-thing is the one for the Flying Spaghetti Monster.

Dammit! I'm so tired of people making perfectly good cars ugly by sticking their damn Darwin fish all over them!

noun. a small metal fish with legs and the word "darwin" inside it, usually placed on the back of a car, partly in order to mock jesus fish and partly to show support for a cruel online scientific community known as the "darwin awards" that awards people who die in the stupidest ways
